4 6-dichloropyridine-3-carbonitrile (CAS# 166526-03-0) Intshayelelo
-Inkangeleko: 4, lulwelo olungenambala ukuya koluthubi olukhanyayo.
-Ukunyibilika: Ine-solubility elungileyo kwizinyibilikisi eziqhelekileyo ze-organic.
-Indawo yokunyibilika kunye neqondo lokubila: indawo yokunyibilika yi -10 ℃, indawo yokubila yi 230-231 ℃.
-Ubuninzi: Ubuninzi yi-1.44g/cm³(20°C).
-Uzinzo: Izinzile, kodwa ugweme ukudibanisa nee-oxidants ezinamandla.
Sebenzisa:
- 4, isoloko isetyenziswa njenge-reagent kwaye iphakathi kwi-organic synthesis.
-Ingasetyenziselwa ukwenza iziyobisi ezifana ne-carbamazepine.
-inokusetyenziselwa ukudibanisa iintlobo ngeentlobo zamachiza kunye nedayi.
Indlela:
- 4, ukulungiswa ngokuqhelekileyo kufumaneka ngokuphendula kwe-chlorination inxalenye ye-pyridine.
-Indlela ethile yokulungiselela inokuthi iphendule i-pyridine kunye ne-benzyl chloride phantsi kwe-acid catalysis, kwaye emva koko i-hydrolyze nge-concentrated aqueous hydrochloric acid ukufumana i-4.
Ulwazi ngoKhuseleko:
- 4, yi-organic compound. Kuphephe ukuphefumla, ukungeniswa okanye ukudibana kwesikhumba.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neglavu zelebhu, iiglasi kunye nempahla yokukhusela xa usebenzisa.
-Xa udibana ngengozi nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
-Landela iinkqubo ezifanelekileyo zokhuseleko ngexesha lokugcinwa kunye nokuphatha, kwaye ugweme ukugcinwa kunye nemithombo yokutshisa okanye i-oxidants enamandla.
